I think people should smile more. There are all kinds of smiles. I have three types. The fake smile, used when I am doing something I don't want to do, like go to work. The real smile that pops up when I am genuinely happy and doing something I enjoy, like enjoying a good joke or a sweet gesture. Then there is the sex smile, which I have never seen for myself but have been told about it. That smile is pure bliss. Smile people.
